<h2><b>max()</b></h2>
<p>
<code>max(<i>expr, dim1, dim2 <,tinc></i>)</code>
<p>
Returns the maximum of <code><i>expr</i></code> over the specified 
dimension range. If the specified dimension is time, an
optional time increment <code><i>tincr</i></code> may be specified.

<p>
<ul>
<code><i>expr</i>&nbsp;&nbsp;&nbsp;&nbsp;</code>- any valid GrADS expression <br>
<code><i>dim1</i>&nbsp;&nbsp;&nbsp;&nbsp;</code>- the starting dimension expression<br>
<code><i>dim2</i>&nbsp;&nbsp;&nbsp;&nbsp;</code>- the ending dimension expression<br>
<code><i>tinc</i>&nbsp;&nbsp;&nbsp;&nbsp;</code>- optional time increment<br>
</ul>

<p>
<code><i>dim1</i></code> and <code><i>dim2</i></code> are standard
GrADS dimension expressions whose dimensions must match.
